Abstract: A novel dual-mode two-way clutch is provided which is capable of locking two relatively rotatable members from being rotated in any one of first and second directions opposite to each other, but which when an external force is applied, the clutch is in position to allow the rotatable members to rotate relative to each other in any one of the first and second directions.

Abstract: An organism vibration measuring device is for measuring a vibration of a portion of an organism which is put in an alternating magnetic field. The organism vibration measuring device includes a vibration detecting member, having a structure suitable for attachment to the portion of the organism, for detecting the vibration of the portion of the organism which resonates under an influence of the alternating magnetic field. It further includes a vibration measuring member for measuring the vibration state of the portion of the organism on the basis of a detection signal from the vibration detecting member.

Abstract: An in-cylinder pressure sensing apparatus for a multi-cylinder engine has a plurality of sensing parts packaged between a cylinder head and a cylinder block of an engine having a plurality of cylinders and being operative to detect a signal indicative of an internal pressure of each of the plurality of cylinders. A detection circuit is provided for connecting the sensing parts in series and for overlapping detection signals obtained from the individual sensing parts to take out a resulting overlapped signal. A reference signal generator operates to supply a reference signal for separating detection signals corresponding to the individual cylinders from the overlapped signal. A unit is also provided for separating the detection signals, detected in accordance with pressures of the individual cylinders, from the overlapped signal on the basis of the reference signal.

Abstract: A one-way clutch operates stably even while an engine is revolving at a speed that tends to resonate the springs of the clutch. The clutch has an outer ring formed with a plurality of cam surfaces on its inner periphery at equal intervals in the circumferential direction. An inner ring mounted in the outer ring has a cylindrical outer surface that faces the cam surfaces. Wedge-like spaces are defined between the cam surfaces an the cylindrical outer surface. Rollers and springs are mounted in the wedge-like spaces so that the rollers are biased by the springs toward narrower ends of the wedge-like spaces. The springs are made up of at least two different kinds of springs having different spring constants. Thus, even if one of at least two kinds of springs should resonate, the other springs will reliably keep the rollers locked between the cam surfaces and the cylindrical surface or move them to unlocked position. The life of the clutch is thus increased.

Abstract: A torque limiter adapted to be automatically reset after a long period of time. The inner ring (1) has a cylindrical surface (5). A polygonal engaging surface (9) is formed on the outer ring (2) by a leaf spring in the shape of a polygonal ring. A cage (11) having pockets is provided between the inner and outer rings (1, 2). Rollers (13) received in the pockets are adapted to engage the cylindrical surface (5) and the engaging surface (9) at the narrowest portions.

An annular portion (20) of the cage (11) is brought into contact with an annular portion (19) of the outer ring (2). As the torque increases with the rollers (13) engaged, the leaf spring (8) is deformed and the rollers (13) pass through the engaging positions, so that the clutch is disengaged.

The rotary unit has an inner member having an outer periphery formed with a raceway groove and a pair of cylindrical surfaces on both sides of the raceway groove, and a cylindrical outer member having an inner periphery formed with a raceway groove and a pair of cylindrical surfaces on both sides of the groove. A retainer mounted between the inner and outer members has a plurality of circumferentially spaced pockets each housing a rolling member and sprag housing recesses provided alternately with the pockets. In each recess is received a sprag having both ends thereof resting on the opposing cylindrical surfaces and biased by a resilient member so that its inner and outer arcuate surfaces contact the cylindrical surfaces. By arranging the sprags and the rolling members alternately with each other in the circumferential direction, it is possible to reduce the entire axial length of the rotary unit.

Abstract: A system for electronically storing and retrieving information. Information is scanned into the system and a user manually designates that the information is to be sorted using boxes which are like folders, sorted by date, or sorted by a card such as by cards which are arranged alphabetically. When the user manually indicates that the information is to be sorted by box, there is also an automatic sort by date and by card. In this case the card which is used is a temporary sort card which is automatically designated. When the user manually indicates that the sort is other than by box, the information is automatically sorted into a temporary box. After the information is stored and sorted, the information can be retrieved and printed, as desired. The system utilizes a scanner, processor, storage device and printer.

Abstract: When a data transmission request is generated, a transmission capable counter indicative of a data length C1 of data which can be transmitted at a certain time point is checked and, when a count value is positive, transmission data Cs is subtracted from the value of the transmission capable counter and a transmitting process is started by a line transmission processing section. When the value C1 of the transmission capable counter is negative or 0, the transmission data is held in a transmission holding data queue. When a fundamental timer times out, if the value C1 of the transmission capable counter is positive, a value C2 of a transmission throughput counter is preset. If the value C1 of the transmission capable counter is negative or 0, the value C2 of the transmission throughput counter is added to the value C1 of the transmission capable counter.
